Five, actually. This showed up on a listserv I’m a member of:
NCSE and The Panda’s Thumb are recruiting scientists named Steve, or Stephanie, or Stephen, or Esteban, et al. to join Project Steve, a tongue-in-cheek response to creationists. All members of Project Steve agree with the following statement:

Evolution is a vital, well-supported, unifying principle of the biological sciences, and the scientific evidence is overwhelmingly in favor of the idea that all living things share a common ancestry. Although there are legitimate debates about the patterns and processes of evolution, there is no serious scientific doubt that evolution occurred or that natural selection is a major mechanism in its occurrence. It is scientifically inappropriate and pedagogically irresponsible for creationist pseudoscience, including but not limited to “intelligent design,” to be introduced into the science curricula of our nation’s public schools.

But you can only sign it if you have a doctorate and are named “Steve” or some variation thereof. At last count they had 895 members and are pushing to cross 900 so they can make new t-shirts that say “more than 900 Steves support evolution”. So please pass this message to any scientists or academics that you know named “Steve” (et al.) and urge them to join up.
